Ok guys I'm having a really simple problem, its part of a school project.
I have a piece of string, on one end is a 50gram weight, the other is a toy car.
The toy car is going to be on the table, and the weight is going to be held by me until I decide to let go. I know dropping the weight will make the car move.
I know the velocity of the car is the same as the velocity of the weight (the string is going to be fully strechted the whole time).
What I want to do is to multiply the velocity of the car and therefore the weight by 2. How would I go about doing this? Do I need to include other factors like height of table or should I change the weight to double the speed?
I think [itex]E_g =mgh[/itex], [itex] v^2=2as[/itex](u=0), or something else may come useful here but I can't do it.
NOTE: Ignore friction.
Thanks guys
